OF WATERBURY, CONNECTICUT, A COR- Specification of Letters Patent.

Application filed September 4, 1907. Serial No. 391,309

To all whom'it may concern:

Be it known that I, GEORGE citizen of the United States, residing at Waterbury, in the \county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Machines for Fastening Hooks and Eyes on Cards, of whichthe following' is a specification.

This invention relates to improvements in machines for fastening hooks and eyeson the general type of machine being that described in Letters Patent Nos; 710,517, 710,518, and 710,519 granted to me on October 7th, 1902. 4

In particular my invention relates to im- RowBo'r'roM, a.

provements in the control of the hook and eye feeding means by the card feeding means, and furthermore, to'an improvementfor finishing the form of the hooks'after thiiy have been sewed on the card.

the accompanying drawing only those parts of the machine are shown as are directly'connected with the improvements and I necessary to show their operation; the general arran ement of the machine is otherwise s'ubstantia l the same as shown and described in t e patents above referred to.

Referring to the drawings: Figure 1 is .a rear view of the central part of the machine, showin the presser foot for finishing the hooks; scale of the presser foot, showing the foot in elevated position ready to finish'the pair of hooks which has "just b 'en sewed on the card; Fig. 3 is a detail r ar view to a still larger scale of the lower portion of the presser foot showin its position when it has finished the form 0 the pair of hooks, shown in Fig. 2 in unfinished state; Fig. 4 is a side I mg themanner in which the hook and eye feeding means are operated and controlledby the'card feeding means.

It has been found that in sewing the so called hump hooks on cards considerable difficulty is encountered causing the machine to pull the eye, when engaged bythe hook,

ig. 21s a detail rear view to a larger past the hump of the book, when same is in 1ts normal sha e, that is,.having the bill in parallel tothe body; For this reason hump without difiicul'ty past the hump. In this.

unfinished state the hooks are sewed on the card, and I provide the following'means for bending the bills of the hooks down after the sewing process, so that they will be 1n parallel to the body of the hook and the hook will leave the machine in the normal shape in which it is used g In Fig. 1, 1 is the main supporting table of the machine on which the sewing table 5 is disposed in the middle within frame 2which is also fastened on tablel. Transversely to sewing table 5 is disposed universal shaft 7 from which the difierent devices comprlslng the machine are operated. On cross bar 3, which is fastenedon frame 2, is fixed bracket 9 (Fig. 4) on which bell crank 10 is pivoted by pivot pin 11. On the left hand arm of hell crank IQ is disposed set screw 12 to abut against the-upper end of bar 13 of presser or stam I foot 14 which bar is slidlngly dlspose in a guide sleeve 15 suitably mounted on bracket 9. A spring 16 is provided between pin 17, and pin 18, fastened on sleeve 15 and presser foot 14, res ectively, tending to hold the foot in elevate lposition. On universal shaft 7 w ich 1s 'sultably driven is disposed cam disk 25, provided with a cam 26. Near disk 25 is mounted forked arm 27 to have its forked end guided between disk 25 and disk 19, the latter also mounted on shaft 7. Near its forked end is fastened on arm 27 cam rollerv28, which is adapted to roll on cam disk 25. The other end of arm 27 is connected to the righthand armof bell crank 10, so that when cam 26 engages and lifts roller 28, arm 27 will be thrown into the osition indicated by dotted lines in Fig. 4, t us also rocking bell crank 10 and throwin same .into the position indicated by dotte lines. This will move the presser foot 14 downward into the position indicated by dottedlines After a pair of hooks and eyes has passed 3 the machine frame the sewin mechanism, and been sewed to the card 29, t e card feeding mechanism passes this pair of hooks and eyes underneath At this instant the,

presser footie (Fig. 2). bills 30 of the hooks are still bent upwards. As soon as the hooks arrive under the presser foot, cam 26 lifts roller 28 and causes presser foot 14 to descend, and to flatten the bills of the hooks down so that they stand in parallelto the hook body, as shown in Fig. 3.

The machine is timed so that a stitch is made by the sewing apparatus every half revolution of shaft 7. Furthermore two stitches are required to sew one pair of hooks and eyes on the card. Since only one cam 26' eyes, as shown in Patent No. 710,517, takes place singly near the end of both chutes; that is to say, means are provided near the end of each chute which will feed one single hook and eye at the time when re uired by the machine. I have now provi ed novel means by which these single hook and eye feeds are controlled by the device feeding the cards to the sewing line of the machine. These meansare illustrated in Figs. 6 and 7. There is shown in Fig, 5, the sewing table 5 on which and within which the card feeding mechanism is mounted, This mechanism, which may be of any suitable kind, such as, for instance, described. in my Patent No. 710,519, is suitably operated by universal shaft 7 and arm 31, which causes through its rocking motion lever 32 to' move ratchet wheel 33 in the direction indicated by the arrow, which wheel in turn transmits its etc by step motion to toothed wheels 34:, 35 an 36, by which the card feed rollers are driven. From tooth wheel 36, the step by step motion is also transmitted by means of tooth wheel 39 to shaft 37, on which the toothed wheel 38 is fixed, (side view of which notches of toothed wheel 38 when lever 47 is drawn downwardby tension spring 59. To the free endof lever 47 is pivoted bar 51, which in turn is pivotedat its upper end to 52. Arm 52 is fastened on rocking 53, jonrnaled bracket 5dfixed to c At or 0n. yoke 46 is provided shaft 53 is further fastened downward pointin arm 55 engaging with its slotted free on pin 56 of slide 57 which may con trolthe eye feed in any suitable manner, such as for instance described in my Patent No. 710,517, while at the other end of shaft 56 is fixed downward pointing arm 58 enga ing with its slotted free end pin 59 of sli e 60, which controls a single hook feed of any suitable kind, such as for instance also described in my patent above referred to.

J Y Jfhllifwhb QUE It will now be seen that if toothed wheel 38 revolves with shaft 7 in the direction indicated bythe arrow (Fig. 6) yoke 46 and its lever will perform a rocking motion owing to the screw 49 dropping into the different notches of toothed wheel 38, which rocking motion is transmitted by bar 51 to shaft 53 and arms 55 and 58 (Fig. 7) This will cause the slide 57 to operate the eye feedin device, and slide 60 to operate the hook feeding device, the timing of both device, being such that at the same time when an dye is fed to theend of the eye feeding apparatus 61, a hook is fed to the end 62 of the hook chute into the proper position to be received by the gripper 63, described and shown in detail in my Patent No. 710,517.

The gearing from the card feeding mech- V moves one tooth in the direction of the arrow, so that rocking arms 55 and 58 operating the hookand eye feeds,' as described above, will complete each one full feeding stroke, within which time, owing to the gearing of the card feed rollers, the card has made two feeding steps, one step for each sewing eye of the hook and eye. The result of this is that one single hook and eye has been fed by the hook and eye feeding devices into position to be placed by the grispper on the card.

ince in this machine twelve pairs of hooks and eyesare to be sewed in one row on one side of the card, toothed wheel 38 is provided with twelve teeth. After one row of hooks and eyes has been sowed to the card,

two closing stitches have to be made idle by the machine into the card; and furthermore,

ing the hook and eye feed. Since nowfour feeding motions of the card feed correspond with the feeding of two pairs of hooks and it eyes on one row, it provide on toothed wheel 38 a notch 65, equal in its size to the space which two teeth occupy on the circumference the combination, with' four idle stitches mentioned above. The po-- sition of notch.65 of wheel 38 is timed relatively to the position of the card in the card-feeding mechanism described in my patents so' that in cooperation with the-first two of the four idlestitches, the card-feed performs the last two feeding steps for one card, while in cooperation with the follow-s,

ing tWo idle stitches, the card-feed performs the first two feeding steps for the nextcard, be made. at the Thus, two idle stitches willend ofthe first card and two at the beginning of the following, card.
